There appears to be a leaked review out there on the net, backed up by pictures. Not sure if am allowed to post here. GTX 680 looks to have about 10-20% performance increase over the 7970 in general. NDA is rumoured to be lifted next thurs or fri

Just went over that leaked benchmark and it looks promising but i've learned to take these sort of things with some salt lol. Still promising though! And apparently the NDA lifts late next week, or so I read.

Edit: No mention of temperatures, acoustics, or OC'ing abilities yet.

Also, i'm not sure if it's been said anywhere else but a huge new feature for these Nvidia cards is that they now natively support 4 monitors per card. Let's hope it's a solid implementation!
